摘　　要：齿槽转矩是一种特殊的转矩,它是由永磁体和定子齿槽之间的相互作用引起的。在电机运行时,齿槽转矩会对电机的效率和稳定性产生负面影响,导致电机振动和噪音增加。本文采用能量法和有限元仿真分析不同极槽配合对电机齿槽转矩的影响,通过优化极槽配合数和磁极偏心距离,有效降低了齿槽转矩,并将仿真结果与样机测试数据进行了对比,证实了优化方案的可行性。研究结果表明,合理选取极槽配合并结合磁极偏心的方法可以有效减小齿槽扭矩,提高电机的性能和稳定性。因此,该研究对于优化电机性能和稳定性具有重要意义。Tlot torque is a special torque in permanent magnet motor,which is caused by the interaction between the permanent magnet and the stator groove.When the magnetic field on the permanent magnet interacts with the stator groove distribution,an additional torque is called the groove torque.Based on the analysis of energy method and finite element simulation,the influence of different pole groove coordination on the motor groove torque,calculate the optimal number of pole groove fit,and further reduce the groove torque by comparing the simulation results with the prototype test data to confirm the feasibility of the optimization scheme.The results show that it can reduce the groove torque.
